Have you ever worked in aerospace: NO, I'm sure, but I have.
Have you ever been in the factories where airline seats are made: I have.
Have your ever talked to or dealt with the FAA: I doubt it.
My consulting company did a STC on a B707. It was signed off by the FAA, FCC and Boeing.
Have you ever flown a plane, with responsibility for people's lives: they are called SOB's by the FAA; that is for Souls On Board. I have.
Have you ever had a battery explode in flight, hit a wind shear and the plane 'go knife-edge' in the blink of an eye while on final approach? I have, w/ passengers.
Do you understand STATISTICAL DISTRIBUTION? Are you familair with the BELL CURVE? When we do the statistics, we don't have to worry about the popluation of 'mixes' such as 2 x 100's. We worry about an abnormal distribution of the small numbers expected at the high end (right side) of the curve. If large numbers of the 300+ pound people show up, then something may have to be done. That's why we set a mental note to check peopel over certain sizes.
Smaller planes hit this limit rapidly, larger planes have more margin.
Don't mention peace and Christ the same day that you go 'Oh, Please' in condescension and ignorance.
